Drum Transcription in the presence of pitched instruments using Prior Subspace Analysis.
This paper demonstrates of Prior Subspace Analysis (PSA) as a method for transcribing drums in the presence of pitched instruments. PSA uses prior subspaces that represent the sources to be transcribed to overcome some of the problems associated with other subspace methods such as Independent Subspace Analysis (ISA) or sub-band ISA. The use of prior knowledge results in improved robustness for transcription purposes and enables the method to work more readily in the presence of pitched instruments than other subspace methods. The effectiveness and robustness of PSA as a tool for drum transcription in the presence of pitched instruments is demonstrated in a simple drum transcription algorithm.
